Recognition of false alarms in fall detection systems [PDF]
, 2011 Falls are a major cause of hospitalization and injury-related deaths among the elderly population. The detrimental effects of falls, as well as the negative impact on health services costs, have led to a great interest on fall detection systems by the ...

The neuronal and synaptic representations of spatial release from masking in the rat auditory cortex
Frontiers in NeuroscienceIn complex acoustic environments, both humans and animals are frequently exposed to sounds from multiple sources. The detection threshold for a target sound (or probe) can be elevated by interference sounds (masker) originating from various locations ...

Study on the Influence of Water Color on Signal Directionality in Laser-Induced Acoustic Processes
Journal of Marine Science and EngineeringImplementing information encoding in laser acoustic signals by altering the medium’s color is one of the current hot research topics. Modulating the color of the medium can modulate the directionality of laser acoustic signals; however, there has been ...

禁核试核查国际监测系统中的USRK及KSRS台阵对朝鲜地下核试验场的地震信号检测能力评估
Dizhen xuebao, 2018 根据禁核试核查国际监测系统中的USRK及KSRS台阵的实际记录数据，统计建立了这两个台阵的本底噪声水平分布概率模型。基于地下爆炸的源频谱模型及比例关系，对2009年5月25日朝鲜核试验在这两个地震台阵上的实际记录信号幅值进行了比例折算，得到了更小震级的“朝鲜地下核试验”在这两个地震台阵上的多频带信号幅值。在3倍信噪比检测条件下，利用概率模型法分别得到了这两个地震台阵对朝鲜地下核试验场小震级地下核试验的多频带信号检测能力。结果表明，震中距在400 ...

Detection thresholds for isolated vowels [PDF]
The Journal of the Acoustical Society of America, 1989 A series of experiments on the detectability of vowels in isolation has been completed. Stimuli consisted of three sets often vowels, one synthetic, one from a male talker, and one from a female talker. Vowel durations ranged from 20–160 ms. Thresholds for detecting the vowels in isolation were obtained from well-trained, normal-hearing listeners using
